Résumé

An experimental research on the impaction of ferrum based nanoparticles on an air-source heat pump water heater (ASHPWH), which uses R-425A/mineral oil VG22, as the working fluid, is presented in this paper. Some surfactants, such as S-80 and PK, were used as dispersants to make the ferrum based nanoparticles disperse well in the oil. The method how to disperse the NiFe(2)O(4) nanoparticles into the mineral refrigeration oil is presented in detail. Performances of the ASHPWH system, such as energy consumption, heating capacity, the discharge pressure, the discharge temperature and so on, are tested. The mixtures of R-22/mineral oil, R-22/mineral oil VG22/NiFe(2)O(4) nanoparticles, R-425A/mineral oil VG22/NiFe(2)O(4) nanoparticles were employed by the ASHPWH system as working fluid in turn. The results showed that the ASHPWH using R-425A/mineral oil VG22/NiFe(2)O(4) nanoparticles as working fluid can work normally with slightly better performance than using R-22/mineral-oil systems.
